BS170 max safe operating area data sheet: At 5V supply (usb) and estimated 500mW output drain current of 100mA is below DC operation. Does this mean WSPR operation at 5V supply is safe?
I love your radio! Great work the community appreciates.

At 13,8V at full 5W out and in another Session at around 9V for abt. 1 W Out.
To fully answer your question:
If your Antenna has good SWR und you´re in the 80% PLUS Efficiency Range, there´s no danger at all for the BS170´s at Full Power.
